Description

Technical Field

[0001] This invention relates to the field of refrigeration technology, and in particular to a high-efficiency refrigeration system. Background Technology

[0002] Commercial freezers refer to refrigerated or frozen freezers sold exclusively in commercial channels such as supermarkets, beverage shops, frozen food stores, hotels, and restaurants for storing ice cream, beverages, dairy products, frozen foods, and food ingredients. Commercial freezers are highly specialized, requiring not only specific storage temperatures but also excellent display capabilities. A well-displayed freezer can effectively boost sales for the business.

[0003] Currently, commercial refrigerators operate in complex environments, often characterized by high temperature and humidity. This leads to excessive condensation, which is typically drained directly into an evaporation dish and evaporated through the evaporation coils. Any condensate that cannot evaporate is drained into an external collection box for manual disposal. This method results in both a loss of cooling capacity and water consumption within the refrigerator. Refrigerant circulation refrigeration is now the mainstream refrigeration method for commercial refrigerators. The evaporator and condenser are the main heat exchange devices in the refrigeration system, using water and air as the cooling medium. Their working principle is as follows: the high-temperature, high-pressure, superheated refrigerant gas discharged from the refrigeration compressor enters the condenser, where it exchanges heat with the air outside the condenser. The low-temperature, low-pressure liquid refrigerant, through throttling, enters the evaporator for heat exchange, lowering the internal temperature and achieving the cooling effect. However, existing refrigeration systems' condensers, being exposed to outdoor environments for extended periods, are prone to dust accumulation, leading to reduced heat exchange performance, decreased cooling efficiency, increased power consumption, and environmental impact. Summary of the Invention

[0004] To overcome the aforementioned problems in the prior art, this invention proposes a high-efficiency refrigeration system.

[0005] The technical solution adopted by this invention to solve its technical problem is: a high-efficiency refrigeration system, including a compressor, a condenser, and an evaporator. The compressor outlet is connected to the condenser inlet, the condenser outlet is connected to the evaporator inlet, and the evaporator outlet is connected to the compressor inlet. It also includes a first spray device and a second spray device. The first spray device is located below the evaporator and includes a water storage box and a first nozzle. The water storage box is located directly below the evaporator, and the first nozzle is located below the water storage box. The second spray device includes a drain pipe, a dehydrator, and a second spray pipe. The drain pipe transports condensate to the dehydrator, and the dehydrator is connected to the second spray pipe. The second spray pipe extends above the condenser, and a second nozzle is located on the second spray pipe above the condenser. A water collection tray is located at the bottom of the condenser.

[0006] In the aforementioned high-efficiency refrigeration system, the condenser outlet is connected to a dryer filter and a throttling device, and the outlet of the throttling device is connected to the evaporator inlet.

[0007] In the aforementioned high-efficiency refrigeration system, an evaporator fan is provided in front of the evaporator, an evaporator fan top cover is provided in front of the evaporator fan, and a flow channel is provided on the evaporator fan top cover, the flow channel being connected to a second spray device.

[0008] In the aforementioned high-efficiency refrigeration system, the first spray device further includes a first circulating water pump, a first spray pipe is provided below the water storage box, a plurality of first nozzles are provided on the first spray pipe, and a first circulating water pump is also provided at one end of the first spray pipe.

[0009] In the aforementioned high-efficiency refrigeration system, a second circulating water pump is installed on the liquid drop pipe.

[0010] In the aforementioned high-efficiency refrigeration system, the condenser and compressor are both located in the compressor chamber, which is also equipped with a condensing fan. The dehydrator is located on the condenser side near the condensing fan, and the condenser, dehydrator, condensing fan, and compressor are all located on the same horizontal line.

[0011] In the aforementioned high-efficiency refrigeration system, the water tray is connected to the water collection box at the bottom of the freezer.

[0012] In the aforementioned high-efficiency refrigeration system, the liquid drain pipe is installed inside the foam layer at the rear of the freezer body.

[0013] The beneficial effects of this invention are that it discloses a high-efficiency refrigeration system. This system fully utilizes the fact that water vapor in the air condenses upon encountering a low-temperature evaporator. The condensate has a low temperature and a high specific heat, meaning that water releases or absorbs more heat than air when its temperature rises or falls, achieving the goal of energy saving, cleanliness, and cost reduction. Furthermore, this invention pre-cools hot air through water mist heat exchange, delaying compressor operation time, extending compressor lifespan, and reducing energy consumption. It also uses condensate to clean and cool the condenser, improving its heat dissipation performance and enhancing refrigeration performance. Additionally, it cools the compressor, reducing compressor operating rate, lowering energy consumption, and promoting environmental protection and energy saving. Attached Figure Description

[0022] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] like Figure 1-2 As shown, this embodiment discloses a high-efficiency refrigeration system, including a compressor 8, a condenser 6, an evaporator 1, a first spray device 4, and a second spray device 5. The outlet of the compressor 8 is connected to the inlet of the condenser 6. The outlet of the condenser 6 is connected to a dryer filter and a throttling device. The outlet of the throttling device is connected to the inlet of the evaporator 1. The outlet of the evaporator 1 is connected to the inlet of the compressor 8. An evaporator fan 2 is installed in front of the evaporator 1, and an evaporator fan top cover 3 is installed in front of the evaporator fan 2. A flow guide groove 10 is installed on the evaporator fan top cover 3, and the flow guide groove 10 is connected to the second spray device. The compressor discharges high-temperature and high-pressure gaseous refrigerant from its exhaust port. The gaseous refrigerant enters the condenser through the condenser inlet. After cooling down due to water film evaporation and rapid air flow, the gaseous refrigerant condenses into a liquid refrigerant. The liquid refrigerant flows out from the condenser outlet. After passing through the throttling device, the liquid refrigerant flows into the evaporator, realizing the evaporation and heat absorption of the liquid refrigerant in the evaporator, achieving a refrigeration effect.

[0024] This embodiment uses a vertical refrigerator as the carrier, and a first spray device 4 is installed below the evaporator at the top of the refrigerator body, such as... Figure 6As shown, the first spraying device includes a water storage box 401, a first nozzle 403, and a first circulating water pump 402. A first spray pipe is located below the water storage box, and multiple first nozzles 403 are installed on the first spray pipe. The first circulating water pump 402 is also installed at one end of the first spray pipe. The water storage box 401 is located directly below the evaporator. The condensate in the water storage box is sprayed into the air as water mist through the multiple first nozzles. The evaporator fan 2 rotates, causing the hot air entering the evaporator 1 to pass through the water mist below the evaporator 1. The water mist evaporates and absorbs heat under the action of the rapidly flowing air, pre-cooling the hot air before flowing back to the evaporator 1 for further cooling. The condensate that has not completely evaporated after heat exchange flows through a drain pipe to the second spraying device. Figure 3-5 As shown, the second spray device 5 includes a drop pipe 501, a dehydrator 504, and a second spray pipe. The drop pipe 501 transports condensate to the dehydrator 504. A second circulating water pump 502 is installed on the drop pipe. The dehydrator 504 is connected to the second spray pipe. The second spray pipe extends above the condenser 6. A second nozzle 503 is installed on the second spray pipe above the condenser 6. A water receiving tray 9 is installed at the bottom of the condenser. The water receiving tray is connected to the water receiving box at the bottom of the freezer.

[0025] In this embodiment, the condenser and compressor are both located in the compressor chamber, which also houses a condensing fan 7. The dehydrator is located on the condenser side near the condensing fan 7. The condenser, dehydrator, condensing fan, and compressor are all on the same horizontal line. The compressor, condensing fan, and condenser can be arranged front-to-back or side-to-side. The drain pipe is installed inside the foam layer at the rear of the freezer body.

[0026] A second spray device sprays condensate onto the condenser tubes to clean and cool the condenser. The sprayed condensate forms a thin water film on the condenser surface. The rotating condenser fan blows air horizontally from the condenser towards the compressor, causing the water film on the condenser surface to evaporate under the influence of the rapidly flowing air. The compressor discharges high-temperature, high-pressure gaseous refrigerant. This gaseous refrigerant enters the condenser through the inlet and condenses into liquid refrigerant due to the evaporation of the water film and the rapid airflow. The liquid refrigerant flows out of the condenser outlet, passes through a throttling device, and then flows into the evaporator, where it absorbs heat during evaporation, achieving a cooling effect. Some of the water in the water film absorbs heat and evaporates into water vapor; the remainder falls into the drip tray and evaporates on its own or flows to the drip box at the bottom of the unit for manual disposal. Under the action of the condenser fan, water vapor moves from the condenser toward the compressor. The water vapor dissolves in the air to form hot and humid air. The hot and humid air flows to the dehydrator. Under the action of the condenser fan, the hot and humid air collides violently with the dehydrator. The hot and humid air outside the dehydrator exchanges heat with the condensate inside the dehydrator. The hot and humid air liquefies upon cooling and falls into the water collection pan, thus drying the air and preventing hot and humid air from flowing through the compressor chamber, which would make the environment more harsh. This improves the heat exchange performance of the condenser and enhances the cooling effect.

[0027] In this embodiment, the pre-cooling process of evaporative condensate is as follows: The evaporative condensate collection system inside the chamber consists of an evaporator, an evaporative fan top cover, an evaporative fan, and a first spray device. The first spray device includes a water storage box, a first water pump, and a first nozzle. The evaporator is fixed to the top of the chamber with bolts, and an evaporative fan is installed in front of it. The evaporative fan is fixed inside the evaporative fan top cover with bolts. The first spray device is installed below the evaporator, consisting of a water storage box, a first water pump, and a first nozzle in sequence. The water storage box, the first water pump, and the first nozzle are connected by a first spray pipe. The condensate formed by water vapor in the air is collected and stored in the water storage box, and then sucked into the first nozzle by the first water pump. After being pressurized by the first water pump, it is sprayed into the air through the first nozzle to form water mist. The hot air in the air reaches the evaporator through the water mist formed by the rotation of the evaporative fan and passes through the first nozzle. The hot air undergoes heat exchange when passing through the water mist, and the hot air is pre-cooled. Then, the evaporator deeply cools the air and blows it into the chamber through the evaporative fan top cover to cool the objects inside the chamber.

[0028] In this embodiment, the evaporative condensate cleaning and cooling circulation system for the condenser is as follows: Condensate that has not completely evaporated within the housing is guided to a drain pipe through a drainage channel inside the top cover of the evaporator fan. The drain pipe is pre-installed on the back of the inner liner and hidden within the foam layer. The drain pipe carries the condensate from the top of the housing to the compressor compartment. The compressor compartment houses the condenser, condenser fan, compressor, second spray device, and water collection tray. The second spray device consists of a drain pipe, a second water pump, a dehydrator, and a second nozzle, which are connected sequentially by the second spray pipe. The condensate flows through the drain pipe to the dehydrator and then continues to the second nozzle. The second water pump pressurizes the water, which is then sprayed onto the condenser through the second nozzle, cleaning the condenser and forming a thin water film on its surface. The rotating condenser fan draws hot air into the compressor chamber, where it passes sequentially through the condenser, dehydrator, condenser fan, and compressor. Some of the water film on the condenser surface evaporates into water vapor due to the rapidly flowing air, cooling the condenser. The remaining water falls into the drip tray below the condenser to evaporate on its own or flows to the drip box at the bottom of the housing for manual disposal. Under the action of the condenser fan, the water vapor moves from the condenser towards the compressor, merging with the air to form hot, humid air. This hot, humid air flows to the dehydrator, where it collides violently with the dehydrator. The hot, humid air outside the dehydrator exchanges heat with the condensate inside, liquefying into liquid water which falls into the drip tray. This process dries the air, prevents hot, humid air from flowing through the compressor chamber and creating a harsher environment, improves the condenser's heat exchange performance, and enhances the cooling effect.

The scope of protection of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to the present invention within its spirit and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of the present invention.
